That's assuming that the fraction has to be a string (and maybe it does). If it doesn't have to be then you should just be able to do "num + (3/8)" - that will come out with a decimal answer (should be the same answer as Barney's). Converting that answer to a fractional display (assuming you need to do that) will be more difficult I think.
